ing drawing, wherein- Figure 1 is a perspective view of the'portable' lawn sprayer.

Figure 2 is a side elevation of the portable lawn sprayer with parts in cross section and taken'on" line 22 of Figure 1.

Figure 3 is a perspective view of'a hood portion of the device as shown in Figures 1 and 2L By referring to the drawings and Figure-'1 in' particular it will be seen that a portable lawn sprayer has been disclosed which comprises "a wheeled carriage for movably supporting a reservoir of spraying material and means fordirect ing the same against an area to be sprayed. The device comprises a framework l0 positionedat an angle from vertical, the upper end of which is united by a cross member I I having a suitable covering I2 thereon and defining a handle by which the framework In may be moved. The lower portion of the framework l0 directly engages one side of an oval shaped sprayframe I3 and is aflixed thereto at its point of contact therewith. The framework III also engages and isafiixed to an axle M which is positioned transversely with respect to the framework Illandhas a pair; of ground engaging wheels l5 positioned on the outermost ends thereof. Apair of transverse cross members [6 and I! are positioned on the framework 19 in spaced relation I to one another and a basket I8 is positioned midg way between the framework I0 and the cross members I6 and IT to provide a dependingre ceptacle with respect thereto in which, a cone" tainer I9 may be positioned. The container l9 preferably takes the form of a'pump type portg; able sprayersuch as is known in the art and wherein an air pump is formed as an integral part thereof. A separate handle of. theairpump is shown in the drawings- ,and is indicated by,

the numeral 20. Y The framework ID has aforward extension 2! formed thereon which is afiixed nearits outer-1" most ends to the opposite sides of the-spray frame I3. The foremost ends of the forward ex tension 2| extend downwardly below the plane.- of the spray frame l3 and terminate in upturned end 22, the lower rounded portion .thereof form ing ground engaging member determining the spacing of the spray frame l3 with respect to The invention is illustrated in the accompanythe ground or lawn over which the portable lawn sprayer is being moved.

Bracing members 23 are positioned between the framework l and the forward extension 2| to support the same in forward and elevated relation with respect thereto and a transversely positioned support between the forward extension 2| is provided and takes the form of a tubular member 24 closed at its end sections where it joins the forward extension 2| and has a plurality of spray nozzles 25 positioned thereon and a fitting 26 in communication therewith. The spray nozzles 25 are directed downwardly and adapted to extend into the area of a hood 21 which is of an oval shape at its lower open end and rests in an inverted cone-shape thereabove, as best shown in Figures 2 and 3 of the drawings.

By referring to Figures 2 and 3 of the drawings it will be seen that the hood 21 is preferably formed of a wire frame 28 and suitable sections of impervious material such as a flexible, transparent plastic 29, the hood 2'! being attached to the spray frame l3 as by lacing the same thereon as shown in Figures 1 and 2 or by otherwise af-- fixing the same thereto. The spray nozzles 25 are positioned within the area enclosed by the hood 21, the periphery of the area being defined by the spray frame i3. The fitting 26 on the tubular member 24 communicates with a flexible tubular member 30 which also communicates with a, valve 3| affixed to the framework near the handle portion ll thereof. A secondary flexible tubular member 32 communicates with the valve 3| and the reservoir 19 so that when fluid prestion of the same as by wind or the contamination of plants or flowers adjacent the area being sprayed.

By referring to Figure 2 of the drawings it will beseen that the device is constructed so that a balance ismaintained between the framework I0 carrying the reservoir 19 and the forward extension 2| carrying the hood 2'! with respect to the axles I4 and the wheels l5 thereon. Thus only a small percentage of the weight of the device is carried by the operator as the device is wheeled about and the construction makes possible the reversed tilting of the device from the position shown in Figure 2 to that where the framework I0 is horizontal and the spray frame I3 is vertical and in which position the basket l8 rests directly on the ground or other supporting surface and the recharging of the reservoir H3 is performed while the same is in an upright manner. In such position the spray frame I3 is in elevated relation to the ground and the nozzles 25 may be adjusted very easily.

Modifications of the structure will occur to those skilled in the art and one such modification comprises the formation of the tubular member 24 as a separate, unattached unit having the spray nozzles 25 affixed thereto, and which alternate form of the tubular member 24 may be positioned entirely within the hood 2'1 rather than thereabove as disclosed in Figures 1, 2 and 3 of the drawings.

It will thus be seen that a simple and eflicient portable lawn sprayer has been disclosed which may be economically formed and which is easy to use and will efiectively control the application of spray to a given area.

Having thus described m invention, what I claim is:

l. A portable lawn sprayer comprising a framework having spaced upstanding bod members joined at their upper ends to form a handle, a transverse axle positioned therebelow and secured to saidframework, wheels positioned on said axle, a horizontally disposed forwardly extending frame formed on said framework and lying in front of said axle, a forwardly extending secondary frame positioned above the said frame and spaced with respect thereto, an enclosure formed between the said secondary frame and the said frame and nozzles disposed within said enclosure, the upstanding portions of the said framework having a basket secured thereto at right angles thereto, an elongated tank positioned in said basket and extending outwardly and. over. the said axle, and means establishing communication between the said tank and the said spray nozzles.
